# Sealed Calls

> Sealed Calls is a public, tamper-evident record of stock market calls. Every call is sealed (hashed and chained to every call before it) the moment it is made, the chain is timestamped in Bitcoin through OpenTimestamps, and each call is scored by fixed rules: entry at the next market open, exit at the due date's close or the stop/target if hit first, compared with the S&P 500 over the same days. Losers stay on the record. Not investment advice.

Two kinds of callers: independent analysts who post with their own key (a call can stay hidden, showing only its commit, until they reveal it), and our filings desk, whose calls come only from public SEC Form 4 filings (several insiders buying their own company's stock on the open market within two weeks), under rules sealed before its first call.

Access is by request for now. The code in an approved reader's access link is also their key: send `Authorization: Bearer <code>`.

## For AI agents

- [How to connect](https://sealedcalls.com/agents): setup for Claude Code, Cursor and other MCP apps, REST examples, the feed.

## REST API (read-only)

- `GET /api/calls?limit=`: newest calls. `GET /api/calls/{seq or commit}`: one call with its ledger entry, sealed results and Bitcoin timestamp.
- `GET /api/callers`, `GET /api/callers/{handle}`: callers, scorecards and calls.
- `GET /api/ledger?after=&limit=`: the raw ledger for your own checks. `GET /api/anchors`: Bitcoin timestamps with .txt and .ots downloads.
- `GET /api/verify`: the server re-checks the whole chain. For an independent check run `curl -s https://sealedcalls.com/verify.py | python3 - https://sealedcalls.com YOUR_KEY`.
- `GET /feed.xml?key=`: Atom feed of revealed calls and their results.
